WiFi peripheral mode display system

Abstract

A wireless peripheral mode is provided by a host system that communicates to a WiFi infrastructure and, utilizing the same WiFi RF subsystem, also communicates to peripherals. The host system may employ additional RF channels for communicating with high bandwidth peripherals, such as display devices, where high levels of QoS may be managed locally. The host system may be a conventional desktop computer system, a notebook computer system, a multi-media access point, a cell phone, a game machine, a portable game machine, a Personal Digital Assistant (PDA), a smart phone or any other type of device that benefits from accessing both a WiFi infrastructure and local peripherals.

The present invention thus effectively and efficiently implements an enhanced wireless peripheral mode.

Problems solved by technology

Developing effective methods for operating wireless electronic peripherals is a significant challenge for modern system designers.

This adds cost to the computer system and if, as is typical, the computer does not integrate the RF chips for peripheral devices, requires the use of an external dongle.

One downside of mesh networking is that it increases the minimum processing capability needed by each mesh device.

While add mesh capability typically would not be a problem for a computer, adding conventional mesh capability for peripherals and in particular for low cost battery based peripherals is a large burden.

For low bandwidth low cost peripherals it is not desirable to either add additional RF channels or increase the complexity of the WiFi features.

However, standard WiFi does not support a host system that can concurrently operate a single WiFi channel for both infrastructure mode and peripheral support.
